The c.893A>G (p.Y298C) alteration is located in exon 9 (coding exon 9) of the NIPAL2 gene. This alteration results from a A to G substitution at nucleotide position 893, causing the tyrosine (Y) at amino acid position 298 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
